PERFORATED PLATE FOR KlTCHEN-SAFES.

$PECIPICATION forming part of Letters Patent No. 307,959, dated November11, 1884.

Application filed July 3, 1884. (No model.)

To all whom it may concern..-

Be it known that I, GEORGE W. KNAPP, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in PerforatedPlates for Kitchen-Safes, ofwhich the following is specification.

My invention relates to an improvement in perforated metal plates forkitchen-safes, and will first be described and then claimed.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a view of an ordinary kitchen-safe having the improvedperforated plates attached. Fig. 2 is a view showing the metal plate inthe first stage of preparation with the ornamental design print-edtherein in colors. Fig. 3 is a view showing the finished metalplate-that is, with the ornamental design thereon in colors andperforated.

Heretofore perforated tin plates for kitchensafes have been punched soas to produce a burr projecting on one surface of the plate. The surfacehaving the projecting burrs constitutes the outer surface, and the plateis secured to the safe with said burred surface out. It will heunderstood that the perforations serve to ventilate, while theoutward-project ing burr about each perforation serves to pre ventinsects frompassing into the safe. These perforations also have been soarranged and disposedas to produce the outlines of figures or designs ofa crudely-ornamental character.

The object of my invention is to ornament the outer surface of theseplates with colored designs, so applied as to avoid obstructing theperforations, and to be protected from defacement by the projectingburrs.

I pursue the following method in producing the improved plate. The plateA, generally of tin, is first painted or printed on one side, in one ormore colors, with some ornan'iental It is immaterial what the particulardesign may be, and the same may be anything that taste or fancysuggests. The design having been de termined on, the same is painted orprinted on the tin plate by any suitable or known means.

A perforatingdie is 'made of the usual kind used in stamping theseplates, which will so dispose or locate the perforations b in the tinplate as will produce in a general Way .a similar design to thatdetermined on, or that will complement or correspond with the saiddesign in colors, the purpose or intention being that the shapes orparts of the design in colors and the shapes or parts of the design inperforations shall supplement each other.-

In other words, my aim is to produce the decorative and ornamentaleffect by the design in colors, and then to locate theventilating-perforations with respect to the features of the saidcolored design so that the beauty of the latter will not be marred orimpaired thereby. The plates having had the design in colors applied anddried, are then perforated by the die referred to, or by other means,the burrs projecting on the surface which has the design. By this methoda handsome perforated plate may be produced at little cost, and theornamental design in colors will be protected from defacement by theprojecting burrs, while the ventilating-perforations will not beobstructed.

Having described my invention, I claim and desire to secure by LettersPatent of the United States 1. The method of ornamenting perforatedplates for safes, consisting in first applying a colored design to asurface of the plate, and then making the ventilating-perforations withrespect to the features of the said colored design, and producing on thesame surface a burr projecting about each perforation, as set forth.

2. A ventilating-plate for safes, having an ornamental colored design onone surface, and ventilating-pertorations with burrs projecting on thesame surface, and so located as to avoid marring the said coloreddesign, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE W'. KNAPP.
